Title: Improvements in or relating to the cutting of multiple-screw threads
IPC: B23G7/00
Filed: 1933-12-15
Abstract: 419,241. Cutting multiple screwthreads. HAHN, H., HAHN, 0., and TESSKY, K., (trading as INDEX-WERKE, HAHN & KOLB), Esslingen - on - Neckar, Germany. Dec. 15, 1933, No. 35287. Convention date, Dec. 16, 1932. [Class 83 (iii).] Lathes.-In a device for cutting multiple screw-threads, a control shaft geared to a lead screw is connected to the work spindle by gearing which is so arranged that the tool in successive traverses engages the different threads until a cut has been taken over each thread, after which the cutting sequence is repeated until the work is finished. The work 1 is mounted on a spindle 2 connected through gearing 3-5 with a control shaft 6 carrying a lead screw 8 and control cams 9 and 10. The latter coact with arms 11, 12 mounted on a member 14 which carries the half-nut 13 and which slides longitudinally on a shaft 15, this movement being transmitted by a fork 17 to a rod 18 connected to the longitudinal slide 19 carrying the tool 20. At the end of the threading operation the cam 9 engages the arm 11 thus rocking shaft 15 which through a threaded connection 21 displaces a rack bar 22 and rotates a cross shaft threaded into a transverse slide 27 which is thus operated to withdraw the tool from the work. At the same time the half-nut is lifted from the lead screw and the tool is returned by a spring 40. The cam 9 then engages the arm 12 to return the tool to the cut. The gear ratio between the wheels 3-5 is arranged so that the tool engages different threads on successive cuts and is varied according to the number of threads to be cut on the work. To accelerate the roughing out of four or six-start threads, cutters having two or three teeth may be employed.

Title: Improvements in or relating to machines for closing cans and the like
IPC: B21D51/26
Filed: 1931-12-24
Abstract: 381,409. Seaming lids to cans. ARMSTRONG, J. J. V., 12, Church Street, Liverpool.-(Continental Can Co. ; 100, East 42nd Street, New York, U.S.A.) Dec. 24, 1931, No. 35649. [Class 83 (iv).] A can-closing machine has a clutch mechanism in the can cover feeding device, which is controlled by the can bodies fed to the machine, in which the clutch includes a driven shaft, a shaft axially aligned therewith for driving the cover feed, a connector intermediate the shafts shiftable axially thereof and maintaining driving connection with one shaft and having an abutment connection with the other shaft for connecting said shafts, and means for shifting the connector to disengage the abutment connection. The cans 2 are delivered to conveyer belts 6 having at one side a bar 26 pressed inwardly by a counter weighted lever 28 and on the other side a spacing screw 25 having an increasing pitch and increasing thread thickness but a constant groove width, which holds the cans securely. The belts 6 travel faster than the screw, and the belt 12, to which the cans are next delivered, travels faster than the belts 6. The cans are thus spaced. They are then engaged by an accelerating turret 41 and a cover 50 is fed from a hopper on to a can, which is next engaged by the clincher turret 43, the covers being clinched on the cans by rolling contact with a segment 45 and the cans ejected by a turret 47. The covers are removed from the hopper by rotating spiral knives, being then picked up by the arms 56 of a turret 57. These spiral knives are connected by a ring gear surrounding the hopper and other gear to a shaft 62, which is connected to a driven shaft 65 by means of the clutch mechanism shown in Fig. 7, which comprises a disc 110 having axial trunnions 111, 112 revolubly fitted within bores 113, 114 in bushing 100 keyed on the shaft 62 and a disc 106 fastened to the shaft 65. An eccentrically located pin 115 extending through the disc 110 has a head 118 against which normally abuts a stud 107 on the rotatably driven disc, thus transmitting motion from the shaft 65 to the shaft 62. When a can is absent from the regular delivery along the belt 12 an arm 92, Fig. 1, normally held as shown by the contact of a rigidly-connected arm 90 with the cans, is pulled to the right by a spring 99 and transmits its motion by a rod 93 and arm 94 to a shaft 95, thus rotating an arm 125 fixed to the bottom of the shaft 95 ; the arm 125 rides along a cam groove 126 on the disc 110, lifts the head 118 out of engagement with the stud 107, and, engaging the pin 115, positively stops rotation of the shaft 62 and hence of the cover feed mechanism. When the supply of cans is resumed the arm 90 is pushed outwardly and the above movements are reversed, the cover feeding operation being resumed.

Abstract: 801,322. Linear dimension gauges. POWELL, G. F. W., and MOLINS MACHINE CO., Ltd. Dec. 13, 1956 [Dec. 16, 1955], No. 36142/55. Class 106 (2). [Also in Groups XVI and XVII] A device for detecting absence, presence or incorrect size of workpieces B, e.g. card blanks for packets, movable in succession in an automatic packing machine, comprises a feeler 4 urged towards a workpiece position, and a strip of magnetic material 9 attached to the feeler 4, the strip 9 having a free end arranged to occupy a neutral zone between two magnetic poles 19 when a correct workpiece B lies beneath the feeler 4 and to be biased towards one side or other of the zone if a workpiece is undersize, oversize, or missing. When the strip 9 is thus biased it will be pulled to the nearer pole 19 and by making contact therewith complete a circuit. As shown in Fig. 2, the feeler is constituted by a roller 4 on an arm 3 of a bell-crank lever of non-magnetic material, the other arm 7 of which carries the strip 9. A spring 5 holds the roller 4 down on to the path P of the workpieces B. A cable socket 22 carries two conductors, one of which is earthed to the device, the other of which is connected with the magnet 16 and so when the strip 9 is pulled to one or other of the poles 19 the circuit is completed, which may be used to stop the machine. A second bell-crank lever 11, 14 (see Fig. 1) is also fitted, one arm 11 carrying a roller 12 co-operating with a cam 13 and the other arm 14 carrying the magnet 16. Thus the magnet 16 is brought to the operative position once in each revolution of the cam 13 and this occurs when a workpiece B is, or should be, present under the feeler 4. In a modification, the strip 9 may be replaced by a pair of strips normally in contact with one another and with stops to limit the movement of each strip to a movement towards the neighbouring pole.
